Opening a work light from a commercial fishing boat (with schematic)

This was one of the hardest things I've tried to open. They must put the glass in with a machine or have specialist silicone injection equipment. I had to Dremel the front of the case off to remove the glass. That means it is effectively unserviceable.

It looks like an expensive and well made light, as the waterproof seals had actually kept the stormy waters of the Irish Sea at bay. The unit had suffered an electronic failure that caused half of the LEDs to be out, and the others were showing signs of age.

These units were replaced with standard LED floodlights which the fishermen prefer anyway, as this unit has a very narrow beam.

It's notable that although the casing was well designed for heat dissipation, there was no thermal compound between the PCB and housing.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
